So the worlds's biggest salt maker has problems with their salt for almost 2 years. From all appearances, they aren't able to correct things for whatever reasons. And their biggest customer keeps recycling canned excuses for the salt.
If all the other salts were gone, we'd have to make our own salt
Here's a starting recipe
For those who are interested, the following artificial seawater recipe is taken from "Chemical Oceanography" by Frank Millero. It makes a recipe that matches 35 ppt seawater in terms of major ions, but does not try to match all minor and trace elements, most of which will be present as impurities in the major elements.
23.98 g sodium chloride
5.029 g magnesium chloride
4.01 g sodium sulfate
1.14 g calcium chloride
0.699 g potassium chloride
0.172 g sodium bicarbonate
0.100 g potassium bromide
0.0254 g boric acid
0.0143 g strontium chloride
0.0029 g sodium fluoride
Water to 1 kg total weight

The "problem" many online guys find doesn't seem to reflect the majority of users, ones like me
I got a few buckets that had low numbers, but since then I've bought 17 buckets which tested within what they said they would. It's estimated online posters make up about MO 5% of sales now, up 4% from a few years ago. Giving it's mainly been a vocal few I highly doubt the problem is as big as you make it out to be. Just buy a different brand if your so hot on the issue.
Do you know how caustic it is mixing your own salt? That will add a whole new level of reefing and knock a major portion of reefers right out of the picture
It will also add a new ailment to reefing that we'll have to watch for
Our guys use full respirators and exposure suits when handling mass salt and adding CA/MG/etc back in.
